With this patch, you will be able to break the borders of your screen by setting a RAM. This is useful if you combine with various other ASM (such as looking around the level or don't want the player to be 8 pixels away with a teleport code when touching the edge of the screen).

It disables the left and right border, as well as the bottomless pit and the top of the screen from setting the player's position and/or killing the player
